Cannot set headers in procedures with fetch adapter

Am i right that with such a setup in nextjs app router route handler:

const handler = async (request: NextRequest) => {
  const response = await fetchRequestHandler({... request ...})
  return response
}

const handler = async (request: NextRequest) => {
  const response = await fetchRequestHandler({... request ...})
  return response
}

It is currently impossible to set headers inside a procedure, cause fetchRequestHandlerfetchRequestHandler just starts to stream proceddure response as body and resolves immedieately, not waiting for it to finish?

That's the behaviour that im observing right now:
1) setting header in procedure and logging
2) logging after await fetchRequestHandler()await fetchRequestHandler()
3) first log is shown after the second one

And headers are not set cause body already started streaming i think
